When you get it unseized it needs a very good battery a good starter motor and easy start they usually go with that original heater plugs are impossible to get but there is a modern conversion that's worth getting it uses car heater plugs.May be a bit hard removing the injectors but with some transmission fluid left in the cylinders and turning it with a bar against the starter ring teeth may just free off, I have the twin of yours plus a few shovel types

How the hell you lot have time to bugger about with such like shite is beyond me .... taken me a year and a half to cobble up a grade beam FFS

Saying that my yards fairly tidy

LOL ... and yeh!! ...... I never seem to have enough time for my 'buggering about' and Pam's constant list of 'to do,s' ...... plus, I don't have to work, as well

The last of these were actually made in 1967, from memory the dozer hydraulics were very low pressure, (probably about 400psi)I think the flow & return piping on the RHS of bonnet is actually half inch BSP threaded water pipe. Home made re usable 'wind in' hyd hose fittings could be used on these as the fittings had a max of 1600 psi constant, 2000psi peak
One of these actually finish graded a 1 in 2 slope working uphill by me.
I unseized a smaller engine by putting diesel down the bores & leaving. (Trax's tip) Also it may help unseizing during the very hot weather as all expands. Rather than burn out a starter motor it may be possible to get engine moving via the main clutch adjustment top plate - more or less between the brake pedals. Will give access to flywheel area. Clutch was dry sadly, they never had the Cat / Allis bomb proof oil clutch. Romneyman / Martin Williams will know much more. I see a makers plate on RHS - but this may refer to the blade itself, as these were an add on - some I think made by Bucyrus Eirie USA or Rubery Owen Darlaston UK
I remember a Ford engine could be transplanted into the BTD6 Drott, think it was the 4D engine, if all else fails

I'm pretty sure that's a Bucyrus Erie blade they were pretty popular with IHC in those days and that's typically how they built the linkages and the adjustable landslide's so you could angle the blade. I'm jealous Rory I've been wanting a small dozer like that for some time I hope it all works out for you. I don't see many of them anymore.
